Ambience Match

Ambience Match lets you match the noise floor of one recording to another recording. Fill in consistent ambience beds under constructed sentences and ADR lines right from within Pro Tools AudioSuite. No more spending hours of time manually looping sections of ambience under a scene with ADR and broken up sentences.

Seamlessly connect dialogue and ADR cuts with real background movement and textures with Complex mode, allowing you to quickly match never before possible ambiences: ocean, wind, traffic, crowds, and more. Or, use Static mode to match stationary ambiences, like a quiet room with a soft hum.

Included in RX Advanced.

Azimuth

Azimuth provides control over left and right channel gain and delay. Azimuth adjustment can help repair stereo imbalances and phase issues that can occur with improper tape head alignment or other speed related issues.

Included in RX Advanced.

The Center Extract module preserves or removes the center channel of a stereo file. Extracting the center will retain the center of a stereo field and attenuate everything on the sides, such as signals panned to the left or right.

Included in RX Advanced.

[REBUILT] De-bleed

It’s never been easier to keep signals clean and separate thanks to the rebuilt De-bleed. Remove classic issues like headphone bleed, or instantly isolate competing instruments and multi-mic’d drum kits using state-of-the-art machine learning – now without needing a reference track. Just let De-bleed find the interference and remove it in a flash. And now, with De-bleed’s new real-time plugin, you can clean up your signal instantly.

Included in RX Standard and Advanced.

De-click

De-click automatically identifies and removes clicks, pops, and digital impulse noises that can ruin a listening experience. Use De-click when polishing audio transfers and other recordings suffering from quality degradation, digital errors, cell phone interference, and more with its low-latency algorithm.

Included in RX Elements, Standard, and Advanced.

De-clip

De-clip repairs digital and analog clipping artifacts. Audio clipping occurs when A/D converters are pushed too hard or magnetic tape is over-saturated. De-clip is extremely useful for reducing distortion in recordings that were made in a single pass, such as live concerts, interviews, and any audio that cannot be re-recorded.

Included in RX Elements, Standard, and Advanced.

De-crackle

De-crackle is designed to treat continuous background crackles in your audio. Use it to remove crackle on vinyl recordings and treat problems like dry-mouthed spoken word or reed noise from woodwind instruments.

Included in RX Standard and Advanced.

De-ess

De-ess audio attenuates or reduces sibilance, the harsh, high-frequency spoken sounds that come from S, F, X, SH, and a soft C. RX includes two modes to remove sibilance: Classic and Spectral.

Classic Mode detects sibilants and attenuates them with a broadband gain envelope. Spectral Mode is more transparent, intelligent, and frequency-specific than Classic Mode. Spectral Mode only attenuates the high frequencies where sibilance is most active, leaving the lower frequencies untouched.

Included in RX Standard and Advanced.

De-hum

De-hum instantly removes any amount of hum, wireless ring, or interference, without artifacts or affecting the audio quality. In one pass, eliminate radio and transmitter interference, camera and generator hum, and more.

The Dynamic Adaptive Mode lets you start getting rid of noise on the go in the Audio Editor. The Adaptive De-hum has high latency and works best in standalone app and offline plugin formats.

In Static mode, you can target hum with a fundamental tone and 16 harmonic bands above it. In Dynamic mode, you can learn and remove any amount of hum with up to 1024 dynamically variable notch filters.

Included in RX Elements, Standard, and Advanced.

De-plosive

Quickly remove plosives with De-plosive. Improve the quality of your dialogue by getting rid of plosive pops and mic bumps that can occur during a recording.

Intelligent analysis detects the presence of a plosive between the desirable harmonics of a dialogue or vocal signal. It then transparently reduces the plosive far more effectively than simply using an EQ to roll off the low end.

Included in RX Standard and Advanced.

De-reverb

Reduce some of the reverb from a recorded space with De-reverb. Salvage dialogue recordings containing too much reverb/acoustic space without needing to spend time/money on a re-shoot or ADR.

Take control over the amount of ambient space captured in a recording: make large cathedrals sound like small halls and make roomy vocals sound like they were recorded in a proper studio space.

Included in RX Elements, Standard, and Advanced.

De-rustle

De-rustle removes the noise or rustle generated by a lavalier microphone rubbing or brushing against a person's clothing during a recording. Lav rustle can vary unpredictably over time and exhibit a wide variety of sonic characteristics, from high frequency "crackling" to low frequency "thuds".

De-rustle uses a machine learning algorithm trained on isolated rustle samples, clean dialogue samples, and dialogue samples with rustle. When processing, De-rustle leverages the trained data to identify and separate the rustle from the dialogue and effectively reduce or remove it.

Included in RX Advanced.

De-wind

Easily remove distracting wind noise from audio with De-wind. De-wind removes the low frequency rumble that occurs when intermittent bursts of wind come into contact with a microphone diaphragm.

Included in RX Advanced.

Deconstruct

Deconstruct lets you adjust the independent levels of tone and noise in your audio. This module will analyze your audio selection and separate the signal into its tonal and noisy audio components. The individual gains of each component can then be cut or boosted.

This can be useful for a variety of audio files and applications, ranging from increasing the “breathiness” of a flute to removing noisy distortion buried among tonal content. The Deconstruct module may produce better results than the De-noise module when the noise is highly time-variable, such as residual vinyl noise after de-clicking/de-crackling has been applied.

The Transient Gain slider adjusts the level of transient components of the signal. This can work as a transient shaper or a de-clicker, allowing you to attenuate or boost clicks and attacks.

Included in RX Advanced.

[IMPROVED] Dialogue Isolate

Make sure your audience hears every word, clear as day with Dialogue Isolate. Now upgraded with state-of-the-art neural nets for finer accuracy across both offline and real-time modes. Whether you’re cleaning up speech for TV, movies, and podcasts – or vocals for your track – it’s never been easier to salvage recordings buried under noise and reverb.

Included in RX Standard and Advanced.

Dialogue Contour

Adjust the character and expressivity of a voice with new levels of control in Dialogue Contour, ensuring that dialogue edits flow seamlessly. Smooth out fluctuations in pitch or tone in voiceover recordings, and seamlessly piece together Frankenbites to create a cohesive performance. Achieve nuanced vocal adjustments and seamless dialogue edits for professional-quality results in both post and music production.

Included in RX Advanced.

Dither

Dithering is a necessary process when converting audio from a higher bit resolution to a lower bit resolution. Dithering is used to tame the quantization distortion that happens when converting between bit depths due to requantization. Dither also preserves more of the dynamic range of a signal when converting to a lower bit depth. The Dither module applies iZotope’s MBIT+ dithering and noise shaping technology to maintain the highest audio quality possible when you are converting to 24, 20, 16, 12, or 8 bits. MBIT+ uses psychoacoustic methods to distribute dithering noise into less audible ranges. The result is a more pleasing sound and smoother fades.

Included in RX Standard and Advanced.

EQ

Make corrective EQ adjustments within RX. The EQ module can often be a simple first step to preparing a file for cleanup and repair. RX's EQ features six fully parametric bands for cutting harsh high frequencies, rolling off low rumbles, reducing standing waves from a boomy location recording, or increasing the intelligibility of dialogue.

Included in RX Standard and Advanced.

EQ Match

EQ Match lets you match the EQ profile of a selection with a different selection. Instantly capture a spectral profile with the offline Learn feature, then apply it to your target audio by selecting Render. This comes in handy if you’re ever tasked with matching a lav mic with a boom mic, matching location dialogue to ADR or vice versa, or for multiple mics on an audio source that you’d like more closely aligned in terms of frequency response.

Included in RX Advanced.

Fade

The Fade module can be used to apply a gradual increase or decrease to gain throughout your selection. Different amplitude curve options are available in the Fade Type menu. For in-phase tonal material, a Cosine fade curve will work well, while the Equal power fade type can be more effective on noisy material.

Included in RX Standard and Advanced.

Find Similar

When you have multiple similar events to repair in an audio file, manually selecting and processing each one can be time consuming. RX includes a Find Similar tool, which will take your selection and move it to the next, or a previous, similar event. The Find Similar tool also has the capability of selecting all similar events at once, allowing you to fix multiple issues at once.

Included in RX Standard and Advanced.

Gain

The gain module is useful for bringing the level of your audio up or down. Gain can also be applied to a specific time-frequency selection, allowing you to manually attenuate or boost selections in the Spectrogram window.

Included in RX Standard and Advanced.

Guitar De-noise

Guitar De-noise helps manage distracting equipment sounds for clean, yet human acoustic or electric guitar recordings. Eliminate distracting amp hum, squeaks from fingers moving across strings, and overly plucky picking.

Included in RX Standard and Advanced.

Interpolate

Interpolate is used for repairing individual audio clicks below 4000 samples in length. This mode replaces your whole selection with the replacement signal. It can be used instead of the “pencil” tool found in other software.

Included in RX Standard and Advanced.

Leveler

Use the Leveler to level the volume of your dialogue with consistency while keeping the breaths and sibilance lower. Take hours of production dialogue and non-destructively level it in just a few minutes, leaving you time for fine-tuning and creative mixing.

Included in RX Advanced.

Loudness Control

Loudness Control is an intelligent automatic loudness control tool built for professional broadcast and post production engineers. Prepare your recordings for final delivery with the detailed level readings, instantly load preset loudness standard targets, conform your production audio to broadcast requirements in seconds, and monitor your levels using the built-in numeric and histogram readouts for integrated, short-term, and momentary loudness. Plus, resize the module to fit your display perfectly and suit your own unique workflow.

Included in RX Standard and Advanced.

Loudness Optimize

Have you ever released a song on a streaming platform and felt like it didn’t sound as loud as your favorite songs? Your loudness may not have been optimized, but RX can help. Loudness Optimize offers an unprecedented approach for controlling the LUFS algorithm to maximize your music’s perceived loudness after normalization.

Due to a gate in the LUFS algorithm, you can lift quiet sections of your music and actually decrease the integrated loudness measurement, resulting in higher level playback on streaming platforms. The Loudness Optimize module features metering to help you understand this gate and its effect, as well as upward compression processing to lift those quiet sections. The Learn function automatically analyzes every opportunity to optimize your song to sound its loudest and best for your streaming listeners.

Included in RX Standard and Advanced.

Markers

Markers and Regions allows you to define and save particular points or selections in time for your audio file. All markers and regions that are created will be saved with your audio file when exporting.

Included in RX Standard and Advanced.

Mixing

The Mixing module provides specific control over both left and right signal and balance levels. This simple operation can be used to downmix stereo material into mono, invert waveforms, transcode left/right stereo into mid/side, subtract a center channel, and much more.

Included in RX Standard and Advanced.

Mouth De-click

Mouth De-click is a de-clicker that is finely tuned to detect and reduce mouth noises such as clicks and lip smacks. It's designed for use on longer audio selections, but it can also be used to remove individual clicks.

Included in RX Standard and Advanced.

[IMPROVED] Music Rebalance

Drums too loud? Vocals too thin? Bass too muddy? Adjust individual mix elements instantly with Music Rebalance, now also available as a real-time plugin. Easily reanimate an existing mix, prep for a remix, or create instrumentals and vocal stems. Split vocals, bass, percussion, and other instruments with pristine source separation – thanks to improved neural nets. Offline or real-time.

Included in RX Standard and Advanced.

Normalize

The Normalize module applies enough gain to set the sample peak level of your signal to the specified Target Peak Level.

Included in RX Standard and Advanced.

Phase

The Phase module can balance asymmetric waveforms by rotating signal phase. Rotating the phase of a signal changes its peak values but doesn’t change its loudness and otherwise has no audible effect on the signal. Asymmetric waveforms can occasionally occur from audio such as dialogue, voice, and brass instruments. Making the waveform more symmetrical gives the signal more headroom.

Included in RX Standard and Advanced.

Plug-in

The Plug-in module enables you to use other iZotope or third-party plugins within RX. This supports the use of VST 3 and AudioUnit (AU) plugins. With a plugin loaded into RX's plugin module, you can make use of the same audio selection tools and Preview and Compare options that are available in other RX modules. This can allow for very detailed processing and greater accuracy when working with your existing plugins, giving you audio selection options unavailable in a traditional DAW setup.

Included in RX Standard and Advanced.

[IMPROVED] Repair Assistant

Clean up tracks faster than ever with enhanced precision. Just select the type of material – voice, tonal/harmonic instruments, percussion, or sound effects – and let RX 12 analyze the audio. Polish dialogue and sung vocals with ease thanks to new machine learning tech, and make final tweaks with deeper controls. Get the best result with different processing suggestions, as well as three different intensities (light, medium, or aggressive) for each. Review and audition different suggestions, hit render, and you’re all set.

Included in RX Elements, Standard, and Advanced.

Resample

Resample allows you to convert an audio file from one sampling rate to another with our renowned Sample Rate Conversion (SRC). SRC is an essential process when converting material from one sampling rate (such as studio-quality 96 kHz or 192 kHz) to another rate (such as 44.1 kHz for CD or 48 kHz for video).

Included in RX Standard and Advanced.

[NEW] Scene Rebalance

Working on a “final” mix that needs less score and more dialogue? Time for some deep, tedious edits, right? Not anymore. Scene Rebalance, built specifically for post production, gives you the power to independently adjust levels and make detailed edits for dialogue, music, and effects in seconds. A real timesaver when the balance needs a tweak. A real lifesaver when you’re editing without stems.

Included in RX Advanced.

Signal Generator

RX includes a Signal Generator that's able to synthesize silence, tones, and noise. This is useful for creating test tones, calibration tones for post production delivery specs, repairing DC offset, and even using it as a “bleep” module to eliminate obscenities in a dialogue edit. The Signal Generator module is capable of generating extremely accurate test tones for research and testing purposes.

Included in RX Standard and Advanced.

Spectral De-noise

Spectral De-noise provides natural noise reduction with unparalleled clarity and control. Built with the most troublesome audio imperfections in mind, Spectral De-noise removes unwanted tonal and broadband noise from any type of recording – such as music, old recordings, home movies, production recordings, and more.

With transparent noise suppression technology that minimizes artifacts, the Spectral De-noise module is carefully designed to preserve the character of your audio. RX features Adaptive Mode, which analyzes changing noise profiles and fixes audio imperfections automatically. It's the ideal choice for fast, efficient audio repair on the fly.

Included in RX Standard and Advanced.

Spectral Recovery

With the increasing prevalence of remote meetings, video calls, and podcast interviews, Spectral Recovery helps restore frequencies above 4k that are removed when the audio is compressed for real-time streaming. Turn once-grainy, inarticulate recordings into crisp, clear conversations.

In RX’s Spectrogram, it’s easy to see the re-synthesized frequency content that Spectral Recovery was able to restore. The Spectrogram itself is resizable, allowing you to click and drag the module for more precise edits. Spectral Recovery improves upon the quality of re-synthesized upper frequencies and can add missing lower frequencies, too.

Included in RX Advanced.

Spectral Repair

Spectral Repair is the key to discovering what your waveform won't show you. Use familiar drawing tools to identify and address problem frequencies and unwanted sounds. Salvage unusable material by filling in audio gaps instantly. With a unique visualization and a variety of selection tools at your fingertips, Spectral Repair lets you get closer to your audio and take a hands-on approach to repairing and enhancing the finished product.

Once a sound has been identified, the Spectral Repair algorithms (available in the module or Instant Process Tool) are able to resynthesize the audio, while taking into consideration tonal harmonics, nonlinear pitch changes like vibrato, background noise characteristics, and transient events. With the power of these tools, you can remove or attenuate unwanted, interfering sounds from barking dogs and breath noises to string squeaks, fret noise, and missed/wrong notes. RX includes a multi-resolution mode that more accurately separates unwanted noise from the desired audio.

Included in RX Standard and Advanced.

Spectrum

A spectrum analyzer uses a fast Fourier transform (FFT) to extract frequency information from a waveform. Depending on the size of the FFT, the signal energy of thousands of frequency bands can be visually represented on a graph. The RX Spectrum Analyzer will show the momentary spectrum of audio around the current playhead position, the average spectrum of a selected time and frequency range, or the real-time spectrum of the audio at the output of RX’s playback.

Included in RX Standard and Advanced.

Streaming Preview

There’s no worse feeling than putting heaps of time into a track only to be disappointed with how it sounds on streaming services. That’s where the new Streaming Preview comes in. Now you can hear your tracks the way the rest of the world will hear them and release with confidence. Just bring your final master into RX 12, open Streaming Preview, select the preset for your streaming platform of choice, and hit Render. Listen to how your track sounds on each streaming platform and compare it with target references. Happy with how it sounds? You’re release-ready. Needs a little work? Jump over to Loudness Optimize or back into your mix.

Included in RX Standard and Advanced.

Time & Pitch

The Time & Pitch module uses the iZotope Radius™ processing algorithm to allow for independent control over the length and pitch of your audio. It is useful for retuning audio to fit in a mix better, or adjusting the length of a selection to account for changes in BPM or timecode.

Included in RX Standard and Advanced.

[NEW] Trim Silence

Editing a series of interviews with inconsistent periods of silence? An audiobook punctuated with long lulls? Normally, this would mean tedious, lengthy edits up against a tight deadline. Now, with the new Trim Silence module, you can automatically detect and delete gaps in audio files. Just set your threshold and let Trim Silence do the rest. 

Included in RX Advanced.

Variable Pitch

Variable Pitch allows you to adjust the pitch of both musical and non-musical audio selections while preserving their time and length. It can be used to change the pitch on the bend of a guitar string, re-shape the sound of a mono instrument, for creative effects on singers, or for sound design. The module features a zoomed-in display of your selection on the Spectrogram, giving you a better indication of the audio you are adjusting.

Included in RX Standard and Advanced.

Variable Time

Variable Time lets you adjust the time stretch amount of an audio selection without altering its pitch. For example, you can modify the tempo of a performance, such as a band or orchestra that is slowing down or speeding up over time. You can also alter time if you need something to be longer or shorter for sync reasons. And since this provides variability over time, you can accelerate or decelerate dialogue, music, and sound effects in a sound design capacity. The module features a zoomed-in display of your selection on the Spectrogram, giving you a better indication of the audio you are adjusting.

Included in RX Standard and Advanced.

Voice De-noise

Restore problematic vocal recordings in real time with RX's Voice De-noise. The zero-latency Voice De-noise is the most powerful de-noiser focused on dialogue and sung vocal treatment. Voice De-noise has an Adaptive mode that can adjust to a changing noise floor in real time, making it ideal for dialogue stem set-and-forget de-noising.

When optimized for music, Voice De-noise excels at attenuating unwanted background noise from air conditioners and street noise from sung vocals in apartment recordings.

Included in RX Elements, Standard, and Advanced.

Waveform Stats

The Waveform Statistics window shows information about the waveform within your current selection. This information can help you find and fix problems like clipping more easily. It is also useful for comparing two similar selections or files. The Waveform Stats window will update to display information about your active track and can remain open as you switch between track tabs.

Included in RX Standard and Advanced.

Wow & Flutter

Audio printed in physical formats (record albums, cassette tapes, film reels, etc.) often degrades as it ages over time. This can result in pitch fluctuations that can hamstring the listening experience. Wow & Flutter is designed to correct these pitch modulations, whether they’re long and drawn-out as in a warped record, or rapid fluctuations like you’d find on aged tape.

Included in RX Advanced.
